I guess I'll start this with the seagraves radiator rehab.
I had the opportunity to work on a 1923 Seagraves firetruck, The radiator was beyond repair and to recore it with the original style honeycomb core would have cost over 6000.00. I proposed to the Gilroy historical society to gut the old core and install a newer readily available radiator from a newer truck. The idea was was that the original external appearance be as if it was original, but it would be just a facade. The firetruck had been in use from 1923 until sometime in the '50's, so it was an important part of Gilroys history.
